From sea to sky this week with my no. 14, the mighty Heuer ‘Bund’ 1550sg.

It’s a beast in size but functionality and legibility are first class.

It has long been thought the ‘3H’ dials were the earliest versions however there is a number that believe the non ’3H’ are the original with the addition of the ‘3H’ coming later as a more obvious warning than the tiny 'T' you see here alone.

Have a great weekend!

Steve
